The Airport Parking "Daily Rate" Trap: $12/Day Is Actually $36 for 25 Hours

Airport lots advertise a headline "daily rate" — but most bill by calendar day, not 24-hour increments. A 25-hour stay at a "$12/day" lot typically triggers three calendar-day charges: $36. A standard 3-night trip (arriving Monday evening, leaving Thursday morning ≈ 3.5 calendar days) can hit 4 billing days at on-airport garages. Off-airport shuttle lots and pre-booking services price by actual overnight rather than calendar entry, saving $12–$24 on a typical trip.
